Owners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements).
Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important
that, in addition to a thorough visual inspection, you check the following points before each ride.

NOTE:
8The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
8Hydraulic brake system
8When disassembling the master cylinder or caliper, always replace the brake fluid. Check the brake fluid
level regularly and fill as required.
8Replace the oil seals on the inner parts of the master cylinder and caliper every two years.
8Replace the brake hoses every four years or if cracked or damaged.
* Since these items require special tools, data and technical skills, they should be serviced by a Yamaha dealer.

98Use only the designated quali-
ty brake fluid. Otherwise, the
rubber seals may deteriorate,
causing leakage and poor
brake performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical
reaction and lead to poor
brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significant-
ly lower the boiling point of
the fluid and may result in
vapor lock. Recommended brake fluid:

Rear brake
Apply the brake and inspect the
wear indicator.
If the indicator reaches the wear
limit line, ask a Yamaha dealer to
replace the shoes.

2. Wear indicator
EAU00732Inspecting the brake fluid
level
Insufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-
fective.
Before riding, check that the brake
fluid is above the minimum level
and fill when necessary.
Observe these precautions:
8When checking the fluid level,
make sure the top of the mas-
ter cylinder is level by turning
the handlebars.

8Brake fluid may deteriorate
painted surfaces or plastic
parts. Always clean up spilled
fluid immediately.
8Have a Yamaha dealer check
the cause if the brake fluid
level goes down.EAU00742Brake fluid replacement
The brake fluid should be replaced
only by trained Yamaha service
personnel. Have the Yamaha deal-
er replace the following compo-
nents during periodic maintenance
or when they are damaged or leak-
ing:
8oil seals (every two years)
8brake hoses (every four years)
EAU00744Drive chain slack check
NOTE:
Spin the wheel several times and
find the tightest position of the
chain. Check and/or adjust the
chain slack while it’s in this tightest
position.
To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and
without rider. Check the slack at
the position shown in the illustra-
tion. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds
40 mm, adjust.

8Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.
8Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, solvent
or thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.8Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
8For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.After riding in the rain, near the
sea or on salt-sprayed roads
Since sea salt or salt sprayed on
the roads in the winter are
extremely corrosive in combina-
tion with water, carry out the fol-
lowing steps after each ride in the
rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads
well into spring.)
1. Clean your motorcycle with
cold water and soap after the
engine has cooled down.
ECA00012
cC
Do not use warm water since it
increases the corrosive action of
the salt.
2. Be sure to apply a corrosion
protection spray on all (even
chrome- and nickel-plated)
metal surfaces to prevent cor-
rosion.
